The number of surgeries of the Roux-en-Y surgery, which is the most powerful type of bariatric surgery, it peaked in 2010.

Right?

So why are you doing less of these surgeries if more and more people are suffering?

Well, clearly it's not working, right?

Because that focused on the calories.

Now, if you focus on the hunger instead, like Ozempic, right?

Because Ozempic works because it decreases hunger.

is very successful.

So you see which one is important.

Do you need to control hunger or do you need to control calories?

And clearly the more powerful effect is the hunger because it's more of the root cause.

So if you think about it this way, there's this concept in logic, which is called the three whys, which is if you really want to get to the heart of the matter, the real underlying root analysis, you have to ask the question why three times.

So you might ask, for example, why did the Titanic sink, right?

And the wrong answer is because it hit an iceberg.

And it's like, why is that wrong?

Well, it's because it's a very superficial sort of first order thinking.

If you simply were to say, okay, then how do we avoid this in the future?

You'd say, don't hit icebergs.

It's like, that's not really very good advice.

It's pretty simplistic, right?
